Toxicity of African locust bean effluent on Oreochromis niloticus
The effects of 96 h sub-lethal concentrations of African locust bean effluent on Oreochromis niloticus were studied using plastic buckets. Packed cell volume (PCY) and histological study of gills and liver were the tissue chemistry parameters investigated. The control buckets contained no effluent. Results revealed increase in ESR (Erythrocyte Sedimentation Rate) decrease in haemoglobin, red blood cell and PCY Yalue of the fish exposed to all sub-lethal concentrations. Damage to liver and gills were noticed in some of the sub-lethal concentrations of all the effluent. Normal situation was observed in all the examined tissues of fish from the control buckets. The African locust bean effluent is toxic on O. niloticus and the lethal concentrations of African locust bean effluent deducted from the 96 hours acute toxicity effect ranged from 3ml.
